Thunderlane has a birthday. Flitter and Cloudchaser are strippers. Blossomforth is a prostitute. 'Porn' tag and 'Mature' rating? I think we can all guess where this is going. For those who can't guess, there will be sex. A lot of sex.

First person pony perspective (Flitter's).

Incest Is Wincest Striptember contest entry. Why tell your twin sister how much you love her when you can show her? Contains pegacest, stripping, prostitution, short skirts (but no explosions), public sex, and happy endings for everypony. Well, everypony but the one who has to clean up the mess.
